Dynamical fission of the quasiprojectile and isospin equilibration for the system 80Kr+ 48 Ca at 35 MeV/nucleon

TL;DR

This paper investigates the dynamical fission process and isospin equilibration in quasiprojectiles produced in 80Kr+48Ca collisions at 35 MeV/nucleon, using experimental data and AMD-GEMINI simulations.

Contribution

It presents the first physics experiment results from the FAZIA Collaboration on quasiprojectile fission and compares data with AMD-GEMINI models to explore timescales of the process.

Findings

Data show isospin equilibration depends on charge asymmetry.

Experimental results align with AMD-GEMINI model predictions.

Insights into the timescale of quasiprojectile fission are provided.

Abstract

Experimental results concerning the dynamical fission of quasiprojectiles in semiperipheral collisions for the system 80 Kr+ 48 Ca at 35 MeV/nucleon are presented. Data have been collected with four blocks of the FAZIA setup in the first physics experiment of the FAZIA Collaboration. The degree of isospin equilibration between the two fission fragments and its dependence on their charge asymmetry is investigated. The data are compared with the results of the AMD model coupled to GEMINI as an afterburner, in order to get hints about the timescale of the process.
